Albert Einstein came up with it, the theory of relativity. He proposed in 1905, the "principle of relativity" as a fundamental property of the universe. No matter what physical process absolute motion at constant velocity was undetectable. The modifications suggested only became significant near the velocity of light, and in day-to-day phenomena it could be ignored. As the velocity of light approached, inertia increased, making it harder to accelerate any matter and setting that velocity as an absolute limit, which no material object could exceed. http://www.pbs.org/wgbh/nova/einstein/relativity/
In November of 1919, at the age of 40, Albert Einstein became an overnight celebrity, thanks to a solar eclipseNote: This feature originally appeared on NOVA's "Einstein Revealed" Web site, which has been subsumed into the "Einstein's Big Idea" Web site. General relativity may be the biggest leap of the scientific imagination in history.With the present accuracy of measurement, the numbers suggest that our universe will keep expanding forever, growing colder and colder, thinner and thinner.
From Newton's laws, two frames of reference moving with constant velocity relative to each other observe exactly the same physical behavior. There exists no way to tell, which of them is moving and which one is at rest: there is no "absolute rest frame" and no "absolute (constant) velocity. " Everything is relative, and either frame can be chosen as reference benchmark. http://www-istp.gsfc.nasa.gov/stargaze/Srelativ.htm
